1. multiple choice: the adult human of average age and size has approximately how many quarts of blood? is it:

a) 4
b) 6
c) 8
d) 10

Explanation:

To determine the correct answer, we recall biological knowledge about human blood volume. An average adult human (of typical age and size) has approximately 4 to 6 quarts of blood, with a common approximation being around 5 - 6 quarts. Among the options, 6 (option b) is a reasonable approximation, but wait, actually, the more accurate common approximation for an average adult's blood volume in quarts is around 4 - 6, and a typical value often cited is about 5 - 6, but the standard range - the average adult has about 4 to 6 quarts, and the most common answer in such multiple - choice questions (matching typical educational content) for the approximate number of quarts of blood in an average adult is 6? Wait, no, correction: The average adult human has approximately 4 to 6 quarts of blood, and a more precise average is around 5 - 6, but in many basic biology questions, the answer is often 6? Wait, no, actually, the correct approximate value for the blood volume of an average adult (in quarts) is about 4 - 6, and the option 'b) 6' is a common choice, but wait, another source: The average adult has 5 to 6 quarts (4.7 to 5.7 liters) of blood. So among the options a)4, b)6, c)8, d)10, the most appropriate is b)6? Wait, no, wait, actually, the average adult blood volume is about 4 - 6 quarts, and a typical answer in such questions is 6? Wait, no, let's check: The adult human body contains approximately 5 to 6 quarts (or 4.7 to 5.7 liters) of blood. So the option b)6 is correct.

Answer:

b) 6
